In the end it is likely to be a matter of what you generally get, rather than the high points, I would expect. We are getting far worse RFnumbers on our connections, and yours would be lovely , and yet we get speedy connections.
Visible:
In the FWIW category: I ran a speedtest between a rural device (BR1 LTE (not LTE-A) with stock antennas, Band 4) and a UpCloud-based fusionhub and got 20Mbps/15Mbps.
Band 4, RSSI: -75dBm SINR: 18.6dB RSRP: -101dBm RSRQ: -8.0dB
Verizon readings on the same tower:
Another device, a BR1 LTE-A (stock antennas) on the same tower but in an RF shadow: 40Mbps/15Mbps
Band 13 RSSI: -65dBm SINR: 9.6dB RSRP: -94dBm RSRQ: -13.0dB
Secondary Band 4 RSSI: -84dBm SINR: 9.0dB RSRP: -100dBm RSRQ: -8.0dB
And a HD2 LTE-A (directed antenna, but with a very long antenna cable run (100 feet)), the antennas being in the same location as the previous BR1 LTE-A: 60Mbps/20Mbps
Band 13, RSSI: -59dBm SINR: 21.6dB RSRP: -92dBm RSRQ: -11.0dB
Secondary Band 4: RSSI: -92dBm SINR: 12.0dB RSRP: -109dBm RSRQ: -8.0dB
And finally, a metro location, Visible on an HD2 LTE-A:
17Mbps/5 Mbps
Band 13 RSSI: -66dBm SINR: -3.6dB RSRP: -99dBm RSRQ: -15.0dB
Secondary Band 4: RSSI: -91dBm SINR: -2.0dB RSRP: -116dBm RSRQ: -17.0dB
Make of it what you will
